The asthenosphere is the middle section of the mantle. The Earth’s asthenosphere is … WebMuch of the continental lithosphere is felsic (i.e. granitic), and normally more buoyant than the underlying mafic/ultramafic mantle. When mafic magma rises through thick continental crust, it does so slowly, more slowly than when magma rises through oceanic plates. This gives the magma lots of time to react with the surrounding country rock. in 1234/2012 anexo i
